Pate nted Sept. 18, 1 945 SMOKING PIPE Walter G. swm, Detroit, Mich. Application September 6, 1944, Serial No. 552,894 v 1 Claim- (01.131-194) This invention relates to smoking pipes.

An object oi this invention is to provide an improved pipe which may have the bowl and stem thereof made out of metal or other suitable material, the bowl and stem being-formed with heat dissipating fins to maintain such parts A further object of this invention is to provide in a pipe of this kind an air intake opening in the reservoir for admitting cool air which will be drawn through the stem with the smoke.

With the foregoing objects and others which may hereinafter appear, the invention consists of the novel construction, combination and arrangement or parts as will be more specifically referred to and illustrated in the accompanying drawing, wherein an embodiment of the invention is shown, but it must be understood that changes, modifications and variations may be resorted to which fall within the scope of the invention as claimed.

in the drawing:

Figure l is a detail side elevation of a smoking pipe constructed according to an'embodlment of this invention,

Figure 2 is a fragmentary longitudinal section taken through the pipe, and

Figure 3 is a sectional view taken on'the line b-t oi Figure 2.

Referring to the drawing, the numeral I designates generally a bowl which is mounted on a reservoir ii. The reservoir II has connected therewith a hollow stem I2 with which a mouthpiece Ilt is connected. The bowl it comprises an upwardly flared cup-shaped body I4 which has the small end thereof lowermost and is formed with a base it. A plurality of vertically spaced apart annular heat dissipating fins I6 are carried by the body M so as to dissipate the heat generated within the bowl It.

The reservoir I i comprises a substantially semiglobular body H which is formed with an upper annular flange I8. A plate I9 engages on the the upper end of the reservoir Ii.

upper side of the flange I8 and is formed with 9. depending annular flange 20 telescoping within The flange 2c is irlctionally held within the upper end of the reservoir I I so that the bowl structure with which the plate I9 is connected may be removed from the reservoir I! for emptying of the latter. The plate i9 inwardly from the outer edge thereof has a downwardly offset plate 2i connected with the plate i9 by an annular flange 22. The flange 1M and the plate 2i form a seat within which a heat insulating disk 23 is adapted to seat.

The base Id of the bowl IIl rests on the heat insulating disc 23 and the bowl I0 is firmly secured to the plate 2i by means of a hollow securing member iii. The securing member 245 has an upset upper end 25 engaging within the bottom of the bowl It and the tubular member 24 extends through a central opening 26 formed in the plate 2! with the opening 26 substantially larger than the outer diameter of the tubular member it so that the plate M will not contact at any time with the tubular member 24.

The plate 2i has extending from the lower side thereof a cylindrical flange 21, and a second heat insulating disc 28 is seated within the flange 2i andis preferably of a thickness greater than the depth of the flange 21 so that a portion of the disc 28 will project therebelow. A washer 29 is interposed between the upset lower end 30 of the tubular member 24 and the lower side of the heat insulating disc 28.

The lower end of the tubular member 24 extends a substantial distance downwardly into the reservoir Ii and the latter is in communication with the bore 8| of the stem I2 by means of a downwardly and rearwardly inclined passage 32. The passage 32 terminates at its upper forward end adjacent the lower edge or the flange 20 and is positioned above the lower end of the tubular member 24. In this manner any liquids within the reservoir 0r collector II will not normally be drawn into the stem I2. An intake vent 33 is provided in the reservoir or collector I I diametrically opposite the outlet passage 32 so that a small amount of air for cooling of the gas or smoke will be permitted to enter the collector I I.

The mouthpiece I3 is formed with a central bore 34 and the forward end of the mouthpiece I3 is reduced as at 35 and telescopes interiorly oi the rear end of the stem I2. The bottom of the collector or reservoir I I is formed with a plurality of heat dissipating flns 36 and the stem I2 is also formed with a plurality of annular heat dissipating fins 31. With a construction as hereinbei'ore described, the bowl and stem may be e out of metal or other suitable material and b having the heat dissipating fins on the bowl,

reservoir and stem, the assembly will be maintained in relatively cooled condition.

In the use of this smoking pipe, the tobacco is placed in the bowl lo and lighted in the usual 1'. As smoke is drawn downwardly by suction on the mouthpiece it, the smoke will enter the collector BI and any moisture from the bowl to will remain in the collector ii. The smoke with a small quantity of cool air entering the collector H through the opening it will pass rearwardly through the downwardly and rearwardly inclined passage 82 and then enter the bore ll 01' the stem 62. Inasmuch as the bore 3! is larger in diameter than the bore 34 a second reservoir or collector will be formed within the stem I 2 forbacco therein, the heat will be dissipated by the annular fins II and any heat which is communicated to the collector II will be dissipated by the heat dissipating nns '36. In like er heat communicated tc'the stem l2 will be rated by the annular heat dissipating fins 8i.

What I claim is:

A smoking pipe comprisinga' bowl, a circular plate below said bowl, a downwardly oiisetsccket formed in said plate, a heat insulating washer in said socket, an annular flange depending from said socket, a second heat insulating washer engaging within, said flange and having a thickness greater than the depth of said flang a second circular plate bearing against the lower side of said second washer, a tubular securing member securing said bowl, said plates and washers together, a liquid reservoir, anannular depending flange carried by said first plate and irictionally engaging insaid reservoir, and a stem extending from said reservoir.
